Product Performance

The module adopts 24-bit high-precision A/D and D/A conversion chips, with a flow signal sampling rate of 1kHz, which can capture small fluctuations in MFC flow in real time, ensuring control command response delay ≤100ms. Integrated with digital filtering algorithm (filter coefficient 0.1-10 adjustable), it effectively suppresses electromagnetic noise in industrial sites and maintains signal stability in the strong interference environment of semiconductor cleanrooms.

It supports two calibration modes: offline and online. Online calibration does not require disconnecting the MFC connection, which can be triggered by Modbus commands. The calibration process takes ≤30 seconds and does not affect production continuity. The fault diagnosis function can real-time monitor faults such as power abnormality, signal over-limit and communication interruption, with fault coverage ≥99%. Fault information is reported through both digital output and communication bus, facilitating quick problem location.

Fully compatible with Brooks SLA5800 and GF125 series MFC, and also supports third-party MFC (parameter configuration required), adapting to multi-brand gas control loops. The mean time between failures (MTBF) is ≥600,000 hours, meeting the 7×24-hour continuous production needs of the semiconductor industry.
